Warnings1.
Connect the power supply according to the safety regulations for electrical operating equipment.
Danger of injury, damage to or destruction of >
the sensor
The supply voltage must not exceed specified
limits. Avoid banging and knocking the sensor. Avoid bending
the sensor rod or the alu tube. Do not transport the sensor on
the sensor rod.
Damage to or destruction of the sensor >
Notes on CE Identification2.
The following applies to EDS eddy current long stroke displacement sensors: EMC regulation 2004/108/EC
The eddy current long stroke displacement sensors satisfy the requirements of the standards
DIN EN 61326-1: 2006-10 and DIN 61326-2-3: 2007-05
The sensors satisfy the requirements if they comply with the regulations described in the instruction manual
for installation and operation.

Unpacking, Shipping6.
Do not take and hold the sensor
at the sensor rod.
Check for completeness and ship-

unpacking.
Installation and Assembly7.
Measuring Tube Guide and Fastening7.1
Mount the measuring tube in the piston borehold.
The dimensions for the measuring tube, see Fig. 4. When the piston
is moved in the measuring tube must not touch the sensor shaft.
Observe the measuring tube position at the zero point (= 4 mA out-
put), see Fig. 2. A slightly eccentric mounting of the measuring tube
has no negative influence on the sensor signal.
Mount the measuring tube in the piston by means of pressing
or glueing.
Spot clamping is not permissable.
